Patented June 421907.

resident of Salida, in the county of Chaffee and State of Colorado, have invented anew and Improved Railway-Tie, of which the following is a full,'clear, and exact description.

This invention relates to railway ties, and the object of the invention is to produce a metal tie of simple construction having a special form which facilitates the fastening of the rails thereto, and which tends to prevent a lateral displacement of the tie in the roadbed.

, The invention consists in the construction and combination of parts to be more fully described hereinafter and particularly set forth in the claims. i

Reference is to be had to the accompanying drawings forming a part of this specification, inwhich similar characters of reference indicate corresponding parts in fall the figures.

Figure 1 is a transverse section through a track laid withniy ties, portions of the body of a-tie being represented as broken away and in section; the rails are also shown in section; this yiew is taken in the plane of the line 1-1 of Fig, 2; Fig. 2 is a plan ofthe parts shown in Fig. 1, a portion of one of the rails being broken anny at the tie so as to illustrate the form of a seat at which the rail is attached to the tie; Fi f. 3 is a cross section through the tie, taken adjacent to one of the rails; and Fig. 4 is a plan showing a frog7 together with the means which I employ for olding the frog in position on the rails.'

Rcferringmore articularly -to the parts, 1 represents a railiray tie which, as illustrated in Fig. 3, has the general forni of a box girder. The tie eoniprisesside plates 2, of channel form, set opposite to each other and parallel. To the upper flanges 8 of these channels, a face-plate 4 is riveted as shown, and to the lower fianges 5. a base-plate 6 is riveted as shown. On the upper face of the face-plate anca-r the position at which the rails 7 are to be attached, I forni seats 8. These seats are substantially rectangular in sha e, as illustrated at the right in Fig. 2,

an formed by means of a `plurality of parallel V-shaped grooves 9 which extend at right angles to each other in such a way that a plurality oi' yramidal projections or teeth 10 are forme( projecting upwardly from the face of the plate, The rail 7 aresecured at these seats by means of chairs l1, the form of which is very clearly illustrated'in Fig. 1. The bodies of these chairs lie closely against the web and flan e ofthe rail, and the outer portions of the c airs are formed into bases 12, the lower faces whereof are formed with a plurality vof teeth 13 which'are adapt-ed to be received in the grooves 9.

At the proper points through the seats 8 I provide slots or bolt openings 14 through which through bolts 15 pass, which effectually secure the chairs to the ties.

attaching such a'frog to a rai1,`acA

In this j vWay the rails are securely clamped between cording to the presentinvention, I provide specialchairs 17 between the points 18 of the frog, v. itch chairs are double-ended; that is, they graspl the rails at both ends of the chair. Under th\e chairs 17 seats are provided similar to the seats 8 described above. These chairs 17 may be considered as double chairs, as both of their ends operate to hold the rail.

Opposite the chairs 17, single chairs 19 are emlployed which hold the outer sides of the rai s, as indicated.

The base-plate 6 of the tie is of special form, tending to prevent a longitudinal shifting of the tie in the roadbed; that is, a shifting laterally of the roadbed. For this purpose, the base-plate is preferably bent so as to 'present a plurality oi4 transversely disposed downwardly projecting V-shaped co1- rugations or ribs 22, which extend, as shown, transversely of the tic, and between these ribs the late is fastened to the flanges 5 by means o suitable rivets 23. When a tie of the construction described is laidin the roadbed, theballast extends into the grooves 24 between the corrugations 22, and ell'octualljf -prevent's'the tie from shit1 ting laterally of the roadbcd. ,l

By reason of the slots 1'4, the position of the chairs may be adjusted to th(l position of the rails; they also allow for the slight en.

project above the saine. These lribs operate to protect the bolts from injuryv by the Wheels in replacing a derailed truck.

ll aving thus described my invention, I

claim new and desire to secure by Letters Patent:

l. A railway tie having a face--plateavith seats for the rails, said seats consistingof a lurality of pyrainidal projections, and chairs bolted to said seats and adapted to clamp the rails therebetween, said chairs having under faces with pyralnidal projections engaging said first projections and preventing the shifting of said chairs upon said seats.

2. A railway tie consisting of a air of oppositelj' disposed channel irons, a ase-plate riveted to said channel irons and havin transversely disposed corrugations forme therein, lsaid base-plate bein attached to' said channel irons between sai corrugations,

a face-'plate attached. to said channel irons at the upper edges thereof and having seats formed on the upper face thereof, saidl seats having a plurality of` yramidal projections' In1 testinionj7 whereof I have-signed- Iny 3o Anaine to this specification in the presence of two subscribingwitnesses; f
